THEODORE W. HANRA'lI-I, -OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-IIALF TO JOSEPH H. 'GOLDNER, 0F CHICAGO, ILLINOIS.

MOP-WRINGER.

To all whom t may concern.'

Be it known that I, THEoDoRE W. HAN- nATI-r, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mop- Wringers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw-ings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in mop wringers, and consists of the matters hereinafter described and vmore particularly pointed out in the appended claims.

The improved mop wringer is oi the kind in which the pressure applied for squeezing the water from the mop cloth or fabric may be applied by the foot, thus obviating the necessity of stooping or bending the body when operatingthe device.

The obj ect of the invention is to produce a device of the kind described, which is eiliciently and easily operated; which is ycheap to manufacture; which in its preferred form provides a movable support for clean water and the dirty water wrung from the mop cloth; and which is collapsible so that it requires 4but little space when put away in the interims oit' its use.

The objects and advantages of the invention will more fully appear as I proceed with the specification.

In the drawings:

Figure 1 is a view presenting a side elevation of a mop wringer made in accordance with the invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a view presenting a longitudinal, vertical section through the mop wringer in a plane indicatedby the line 3 3 of Fig. 2.

Fig. 4 is a view presenting a rear elevation of the improved mop wringer.

Referring now to that embodiment of the invention illustrated in the accompanying drawings indicates the base of the device. Said base consists of a platform 5a, preferably made of wood, provided at or near its four corners with Supporting caster wheels 6, upon which it may be easily moved troni place to place. The base is longer than it is wide, and parallel angle bars 7, 7 are attached to its top along its longer edges with one ange vertical. and lush with said -Specication of Letters Patent.

edges. 7a, 7 a indicate strap irons fixed tothe ends of the base and connected to the yangle bars 7, 7 for strengthening the base.

The platform 5a, as shown, is made large enough to support two buckets, one for clean water Yand one to receive the water wrung from the mop cloth. The wringer mechanism is placed'above the .part or' Ythe platform, that is to be occupied by the last named bucket, and is supported thereon by a collapsible frame, 8a.

The collapsible frame 8 comprises four upright, flat, metal bars 8, 8, 9, 9, pivotally connected to the angle bars 7, 7 of the base; a pair of parallel angle bars l0, extending lengthwise of the base and each connecting, by pivotal pins, an upright S and an upright 9; parallel, spaced angles bars 11, 11 extending crosswise of the base and rigidly connecting the bars 10, lO at or near 'their ends; and a pair of diagonal brace bars lll,

each pivotally connected at its ends to an.

upright 8 and to an upright 9, one of said ends, (the end 14a as illustrated) being'detachably connected to its pivot pin 9a in a familiar manner. The diagonal bars 14C lact to hold the side members of the frame 8n from collapsing. Y

The bars 10, 10 and 1l, 11 forman open frame on which is carried a perforated lplate 13.l Said plate constitutes the stationary member or the wringing device against which the mop cloth is pressed or squeezed and through the perforations oi which, the water pressed from the cloth, drains or drips into a bucket placed below it on the platform 5a. The plate 13, as shown, is attached at its sides to bars 12, 12 (see Fig. 2) which in turn are attached to the cross bars l1 of the frame. Y

The movable member of the wringer consists of a jaw, which, as shown herein, is hinged to the frame and is actuated by Va foot lever to engage a mop head with'the mop cloth attached. Said jaw consists of a dat bar 18a extending crosswise of. the frame and of two parallel, spaced angle bars 18,18 extending at right angles to said bar 18a and each rigidly attached to it at one end. The other ends of said angle bars Yare p ivotally mounted on a crossrod 17 carried by upright bars 16, 16 which are fixed to the angle bars '12, 12 at the sides of the perforated plate 13. 1.9 indicates a cross-rod extending through and engaged in. suitable holes in the bars 18 near their ends and above the jaw bar 18a. Said rod 19 extends beyond the sides of the perforated plate 13 and is operatively connected at its ends by flat link bars 24, 24 to the side arms 21a, 21a of a U-shaped foot lever or treadle 20. Thelever arms 21a, 1a, are located outside the upright members of the collapsible frame and are fulcrumed on a horizontal cross-rod 22 mounted on the uprights 8, 8 and projecting beyond the outer faces of said bars. The jaw bar 18a is normally held in raised position by means of spring controlled levers 25, 25 fulcrumed on the rod 17 to which the said jaw bar is hinged. Said levers engage at one end under the cross rod 19 and at the other end are connected by coiled springs 26 to the cross-rod 22.

The operation of the mop wringer is as follows i/Vith the wringer arranged in its set up position, pails or buckets 27, 28 indicated in dotted lines in Fig. 1, are placed on the platform 5a. The pail 27 containing clean water is placed on the front end of said platform and an empty pail 28 is placed on the rear end of the platform beneath the perforated plate 13. The mop head 29` indicated in dotted lines in Fig. 3 (and which forms the subject matter of a separate application for patent, tiled by ourselves on even date herewith, and bearing Serial Number 146,648) is brought to bear upon the perforated plate 13,-the operator still retaining his hold on the handle. The transverse member of the U-shaped lever or treadle, indicated at 2lb, is now engaged and depressed by the foot. The depression of the lever 20 actuates the links 2e to pull down on the rod 19, which swings the jaw-bar 18a down upon the mop head and forcibly presses it against the perforated plate. The mop cloth on the head is thus squeezed between the bottom of the mop head and the perforated plate 13, and the water is wrung out of it and drained through the perforations of the plate 13 into the bucket or pail 28 below it.

As will be understood, the downward movement of the treadle and of the jaw-bar 18a has been resisted by the spring controlled bars 25. Thus, when the foot is removed from the treadle or foot lever, said treadle, with the jaw-bar, will be returned to its rst position. The upward movement of the parts is limited by the side bars 21a of the treadle striking the pivot pins connecting the uprights 9 of the collapsible frame with the top bars 10 thereof, (see Figs. 1 and 2) which are projected for that purpose.

After the mop cloth has been wrung out and when it is being used for washing purposes, it is again dipped into the clean water in the pail or bucket 27, and the mopping process is carried on in the usual way.

The structure described may be easily moved from place to place on the door which is being mopped, and provides support for both the clean washing water and for the dirty water wrung from the mop. This is of great convenience, as will be readily understood, since, even when drying a floor, it is possible to wash the mop cloth in the clean water carried by the bucket 27 and then wring the mop cloth dry before applying` it to the oor after it. has been washed.

By detaching the ends 14a of the diagonal bars 14 from their respective pivot pins 9E, the collapsible frame may be swung on the bottom pivotal ends of its uprights 8, 9, from the position shown in full lines in Fig. l to the position shown in dotted lines. This, of course, is done after the buckets or pails have been removed from the platform 5B- and puts the apparatus into more convenient shape for disposal in a closet or other place out of sight. The collapse shown is easily brought about by reason of the construction heretofore described.

That the improved wringer may be easily and cheaply manufactured is manifest from the construction of parts described. All of said parts may be made from bar, strap and angle iron which may be bought at any time on the open market and which only requires to be cut to the required dimensions. The remaining assembling and riveting required, demands no expert labor.

l/Vhile in describing my invention, I have referred to certain details of mechanical construction and arrangement of parts, it is to be understood that the invention is in no way to be limited thereby except as may be pointed out in the appended claims.
